(a) chemical reaction; (b) chemical reaction. Sciences, Culinary Arts and Personal Since potassium nitrate is water soluble, it just exists as its free ions which means that these ions do not participate in the reaction and are considered as the spectator ions. Complete and balance the single replacement reactions: This side-effect also lies behind the urban myth that bromide was added to the tea of prisoners and World War I soldiers in order to reduce sexual urges . The pyrite electrode potential showed a sub WebSilver iodide, Agl, precipitates as a yellow soHd when iodide ion is added to a solution of silver nitrate.

Magnesium gets covered with a layer of magnesium oxide when kept in air for a long time. Celebrate the start of summer with a cool treat sure to delight the whole family! Silver bromide is not water soluble, sodium nitrate is. Sodium bromide is represented by the molecular formula of NaBr and the molecular formula of silver nitrate is represented by AgN O3. Sodium nitrate is also soluble in water so after the reaction has occured, sodium and nitrate ions are still floating in solution. Learn more about our Privacy Policy. The slight positive charge on the carbon will be larger if it is attached to a chlorine atom than to an iodine atom. Write down the reaction involved. What is a balanced chemical equation ?
